We have implemented a new VOIP solution and would like to take advantage of some firewall option that are availabe called traffic shaping. In order to do this we need to have our VOIP phones on a different subnet to add a seperate interface on the Firewall. Currently, all systems PCs, VOIP servers/phones are on the same network but our VOIP sever and VOIP phones are on its on POE GB switch. I would like to connect the VOIP POE switch directly into the Firewall. This requires that the phones and server have a different Subnet. Is it possible to have DHCP issue a different IP subnet only for the VOIP phones?
Can I enter the MAC address of the phones so that DHCP can identify them?
